SOUND ABSORBING BODY
To provide a sound absorbing body excellent in cushioning property and design property, capable of exhibiting sound absorbing effect excellent in the sound range of daily life noise, and having excellent reverberation suppressing effect in a low sound range.SOLUTION: The sound absorbing body is formed into a predetermined three dimensional shape by combining a plurality of sheet-like three dimensional knitted fabrics organized from a pair of base cloths spaced apart from each other and connecting yarns reciprocating between the base cloths and connecting them to each other. The three dimensional knitted fabric has a prescribed air permeability, and a hollow part covered with three dimensional knitted fabrics is formed inside the sound absorbing body.SELECTED DRAWING: Figure 1
【課題】クッション性、意匠性に優れ、かつ、生活騒音の音域において優れた吸音効果を発揮し、低音域において優れた残響抑制効果を有する吸音体を提供すること。【解決手段】吸音体は、互いに離間して配置された一対の基布と、該基布間を往復して両者を結合する連結糸とから編成されたシート状の立体編物を複数組み合わせて、所定の立体形状に形成される。立体編物は、所定の通気度を有し、吸音体の内部には、立体編物で覆われた中空部が形成されている。【選択図】図1
